###### Important Notes on 9th Maths Chapter 3

I. In Cartesian system, there are two perpendicular straight lines XX’ (horizontal line) and YY’ (vertical line) which intersect at origin.

II. The x and y-coordinates of a point is the perpendicular distance from the Y-axis and X-axis measured along the X and Y-axes respectively.

III. The y-coordinate of any point X-axis is zero and x-coordinate of any point on Y-axis is zero.

IV. The axes divides the plane into four quadrants.

1. In 1st quadrants x > 0, y > 0 i.e (+, +)

2. In 2nd quadrants x < 0, y > 0 i.e (-, +)

3. In 3rd quadrants x < 0, y < 0 i.e (-, -)
4. In 4th quadrants x > 0, y < 0 i.e (+, -)

### Important Questions on 9th Maths Chapter 3

##### In which quadrant or on which axis do each of the points (– 2, 4), (3, – 1), (– 1, 0), (1, 2) and (– 3, – 5) lie?

(–2, 4): Second Quadrant

(3, –1): Fourth Quadrant

(–1, 0): x–axis

(1, 2): First Quadrant

(–3, –5): Third Quadrant

##### How can we locate the position of an object?

To locate the position of an object or a point in a plane, we require two perpendicular lines. One of them is horizontal, and the other is vertical.

##### What is the coordinates of origin?

The coordinates of the origin are (0, 0).

##### What is the coordinates of a point on x-axis or on y-axis?

The coordinates of a point on the x-axis are of the form (x, 0) and that of the point on the y-axis are (0, y).

##### What are quadrants?

The coordinate axes divide the plane into four parts called quadrants.

##### What are the main points of Class 9 Maths Chapter 3 for first term exams?

The main points for the first term exam preparation from chapter 3 class 9th Maths are:

- To locate the position of an object or a point in a plane, we require two perpendicular lines. One of them is horizontal, and the other is vertical.
- The plane is called the Cartesian, or coordinate plane and the lines are called the coordinate axes.
- The horizontal line is called the x -axis, and the vertical line is called the y – axis.
- The coordinate axes divide the plane into four parts called quadrants.
- The point of intersection of the axes is called the origin.
- The distance of a point from the y – axis is called its x-coordinate, or abscissa, and the distance of the point from the x-axis is called its y-coordinate, or ordinate.
- If the abscissa of a point is x and the ordinate is y, then (x, y) are called the coordinates of the point.
- The coordinates of a point on the x-axis are of the form (x, 0) and that of the point on the y-axis are (0, y).
- The coordinates of the origin are (0, 0).
- The coordinates of a point are of the form (+ , +) in the first quadrant, (–, +) in the second quadrant, (–, –) in the third quadrant and (+, –) in the fourth quadrant, where + denotes a positive real number and – denotes a negative real number.
- If x ≠ y, then (x, y) ≠ (y, x), and (x, y) = (y, x), if x = y.

##### How many problems are there in chapter 3 of class 9th Maths for first tem exams?

In chapter 3 of class 9th Maths, there are three exercises. The first exercise (Ex 3.1) contains two questions, the second exercise (Ex 3.2) contains two questions, and two examples (examples 1, 2), the third exercise (Ex 3.3) contains two questions and two examples (examples 3, 4). So, there are in all ten problems (6 questions and four examples) in chapter 3 (Coordinate Geometry) of class 9th Maths.

##### Is it possible to solve chapter 3 (Coordinate Geometry) of class 9th Maths in one day?
